Abstract

CATALYSEUR POUR LA DESTRUCTION DE L'OZONE. IL EST CONSTITUE D'UN MELANGE A BASE DE MANGANESE, D'ARGENT, D'ALUMINIUM ET D'UN SILICATE, QUE L'ON OBTIENT EN CHAUFFANT A UNE TEMPERATURE DE 300 A 600C UN COMPOSE DU MANGANESE, UN SEL D'ARGENT, DU SILICATE D'ALUMINIUM ET UN META-SILICATE DE METAL ALCALIN, EN PRESENCE D'UN COMPOSE ORGANIQUE POUVANT SUBIR UNE DECOMPOSITION A LA TEMPERATURE DU CHAUFFAGE. CE CATALYSEUR PEUT SERVIR A DETRUIRE L'OZONE DANS L'ATMOSPHERE DE LOCAUX D'ETABLISSEMENTS HOSPITALIERS OU L'ON S'EST SERVI D'OZONE POUR LA DESINFECTION OU ENCORE DANS LES LOCAUX OU L'ON TRAVAILLE AVEC DES SOURCES DE RAYONNEMENT ULTRA-VIOLET.CATALYST FOR OZONE DESTRUCTION. IT IS CONSISTS OF A MIXTURE BASED ON MANGANESE, SILVER, ALUMINUM AND A SILICATE, WHICH IS OBTAINED BY HEATING AT A TEMPERATURE OF 300 TO 600C A COMPOUND OF MANGANESE, A SILVER SALT, ALUMINUM SILICATE AND AN ALKALINE META-SILICATE, IN THE PRESENCE OF AN ORGANIC COMPOUND WHICH CAN UNDERGO DECOMPOSITION AT THE HEATING TEMPERATURE. THIS CATALYST CAN BE USED TO DESTROY OZONE IN THE ATMOSPHERE OF PREMISES OF HOSPITAL ESTABLISHMENTS WHERE OZONE HAS BEEN USED FOR DISINFECTION OR AGAIN IN PREMISES WHERE WE WORK WITH SOURCES OF ULTRA RADIA PURPLE.
